de·riv·a·tive

(dĕ-riv'ă-tiv),
1. Relating to or producing derivation.
2. Something produced by modification of something preexisting.
3. Specifically, a chemical compound that may be produced from another compound of similar structure in one or more steps, as in replacement of H by an alkyl, acyl, or amino group.

derivative

/de·riv·a·tive/ (dĕ-riv´ah-tiv) a chemical substance produced from another substance either directly or by modification or partial substitution.

derivative

[dəriv′ətiv]
Etymology: L, derivare, to turn away
anything that originates in another substance or object. For example, organs and tissues are derivatives of the primordial germ cells. Chemical derivatives may be produced to confirm identification of a compound or to aid in the analysis of a compound.

derivative

the result of the calculation (usually with calculus) of the change of one variable with respect to another. Also alludes to the number of 'steps' of calculus required (e.g. acceleration is the second derivative of displacement with respect to time). See also differentiation.
